Fieldbusses have been the backbone of inter-device communication in both industrial and home automation settings for a few decades. The underlying assumption is the availability of reliable and low-latency communication for all busses. This often implies that the busses are confined to a single physical location. With the advent of the `Internet of Things' (IoT) and succinctly the `Industrial Internet of Things' (IIoT) and the increased demand for control logic to be pushed into the `Cloud', that assumption can no longer be upheld. Since no (I)IoT protocol exists to provide remote control, let alone in a secure fashion, while providing low latency at the same time, we are left with the problem of routing fieldbusses from, say, data-centres to shop-floors. This presents a challenge, because those busses have been designed for safety rather than security.In this paper, we elaborate on the viability of routing layer two fieldbus traffic while providing both: low latency to fulfil real-time requirements and security through cryptographic tunnels. We design and implement a network topology where Profinet traffic is routed through a VXLAN over Wireguard overlay to control a SoftPLC instance. We evaluate our implementation in a realistic test-bed and our measurements indicate that bridging Profinet over VXLAN and Wireguard induces a latency low enough for running time-critical applications.
